Genetically Influenced Trait

•

We are all the products of interactions between our genetic predispositions and our surrounding environments.

A baby who is genetically predisposed to be social and easygoing may, in contrast to one who is less so, attract more affectionate and stimulating care and thus develop into a warmer and more outgoing person.

•

Similarly, a stressful environment can trigger genes that affect the production of neurotransmitters that underlie depression.
